a molecule made up of two chains of nucletides that are twisted together, DNA contains the information that determines the traits that a living thing inherits and needs to live
A
Protein
B
RNA
C
Nucleic Acid
D
DNA
Explanation: 

Detailed explanation-1: -Definition. Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.

Detailed explanation-2: -A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3).

Detailed explanation-3: -Double Helix Double helix, as related to genomics, is a term used to describe the physical structure of DNA. A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape.

Detailed explanation-4: -Many nucleotides bind together to form a chain called a polynucleotide. The nucleic acid DNA (deoxyribonucleic acid) consists of two polynucleotide chains.

Detailed explanation-5: -DNA consist of two strands of repeating units called nucleotides; each nucleotide is made up of a five-carbon sugar, a phosphate group, and a nitrogen base.
